Objective To investigate the effects of Yishen dianpi Yangxue Tongli Fang (YSJP) on IGF-1 mRNA expression in the ovary of PCOS rat, and study its mechanism on the molecular level. Methods Seventy two female SD rats were randomly divided into normal control group, model group, clomifene group and low-, mid-, high-dose Chinese medicine group. The animal model established by capsulae levonorgestreli silasticus was used to observe the IGF-1 mRNA expression in ovary by hybridization in situ. Results IGF-1 mRNA expression of PCOS model group was higher than the normal control group obviously. The semi-quantitative image analysis showed that TCM treatment could decrease IGF-1 mRNA expression. Conclusion Yishen Jianpi Yangnue Tongli Fang could decrease the IGF-1 mRNA expression in ovary and improve the insulin resistance of PCOS rats.

AIM: To study the relative bioavailability of clavulanic acid/amoxicillin dispersive tablets. METHODS: A single oral administration of 125 mg clavulanic acid and 500 mg amoxicillin of dispersive tablet and Anqi tablet to 18 healthy male volunteers in a randomized cross-over study. The plasma concentration of clavulanic acid and amoxicillin simultaneous were determined with HPLC. RESULTS: The pharmacokinetic parameters of dispersive tablet and Anqi tablet for clavulanic acid were: Tmax (0.89± 0.25) h and (1.01±0.30) h; Cmax (1.92±0.64) mg·L-1 and (1.49±0.65) mg·L-1; AUC0→∞ (4.347±1.542) mg·h·L-1 and (3.395±1.468) mg·h·L-1, the pharmacokinetic parameters for amoxycillin were: Tmax (1.15±0.41) h and (1.34±0.40) h; Cmax (5.81±1.40) mg·L-1 and (4.60±1.37) mg·L-1; AUC0→∞ (13.472±3.114) mg·h·L-1 and (11.937±2.735) mg·h·L-1. The clavulanic acid Tmax of clavulanic acid/amoxicillin dispersive tablet was significantly shorter, clavulanic acid and amoxicillin Cmax, AUC0→∞ of clavulanic acid/amoxicillin dispersive tablet were significantly greater than the control Anqi tablet respectively, while there was no significant difference between amoxicillin Tmax of two tablets. CONCLUSION: The bioavailability of clavulanic acid/amoxicillin dispersive tablet is superior to Anqi tablet.

Objective To investigate the effects of mesenchymal stem cells (MSCs) transplantation combining with vascular endothelial growth factor (VEGF) gene therapy on myocardium rebuilding,angiogene- sis,and heart function improvement in rats with myocardial infarction.Methods SD rat MSCs were isola- ted,cultured in vitro,labeled with BrdU and transfected by Ad.VEGF gene.Four weeks after left anterior descending artery was ligated to created rat myocardial infarction,cardiac function was examined with echocar- diography,rats were randomly divided into four groups (n=10 in each group):GroupⅠ:MSCs/Ad.VEGF implantation;GroupⅡ:MSCs implantation;GroupⅢ:Ad.VEGF injection;GroupⅣ:Control.MSCs dif- ferentiation was observed 4 weeks after transplantation.Immunohistochemistry and angiogenesis were observed. Echocardiography was performed to detect the effects on heart function.Results MSCs labeled with BrdU could be identified in host hearts in groupⅠandⅡ,most of them positively stained with cTnT antibody. Echocardiography indicated that the improvement of the LVEF value in groupⅠwas more significant than that in the other three groups (P＜0.01,respectively).Some cells were incorporated into the coronary capillaries in the infarcted region.The capillary density in groupⅠwas higher than that in the other three groups (P＜0.01,respectively).Conclusion MSCs implantation combining with VEGF gene therapy can obviously re- pair damaged myocardium and enhance the angiogenesis in ischemic heart tissue.

AlM: To investigate the effect of endocapsular phacoemulsification cataract extraction and intraocular lens (lOL) implantation with a 1. 8mm or 3. 0mm clear corneal incision on total root mean square ( RMS ) value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film.
METHODS:ln a prospective study, 156 age- related patients ( 196 eyes ) were randomly distributed into two groups. 1. 8mm-group comprised 94 eyes that had a silicone lOL inserted through a 1. 8mm sutureless clear corneal incision, while, 3. 0mm- group comprised 102 eyes through a 3. 0mm clear corneal incision. Postoperatively, the changes in the total RMS value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film at 1wk, 1 and 3mo were determined respectively.
RESULTS:ln both groups, postoperatively at 1wk,there were statistically significant differences ( P<0. 05 ) in the total RMS value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film, while, there were statistically minimal differences ( P< 0. 05 ) between 1. 8mm-group and 3. 0mm-group at 1mo, but were not statistically significantly different ( P > 0. 05 ) between two groups at 3mo postoperative.
CONCLUSlON:This study confirms that incision size has strong impact on the corneal higher-order aberrations, especially, 3. 0mm incision caused significant differences in the total RMS value of cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film compared with 1. 8mm micro-incision, therefore, micro-incision is very beneficial for clinical use in phacoemulsification.
